Abstract
The present invention relates to vehicle-mounted embedded system technical field more particularly to a kind of methods that vehicle-mounted fault diagnosis daily record exports automatically, include the following steps：Create a system thread for monitoring peripheral memory；The system thread detects the key the configuration files whether peripheral memory is stored with troubleshooting log；Detect that the peripheral memory is stored with key configuration files, vehicle imbedding type system verification and the key for reading diagnostic log configure content；Key configuration contents are output to peripheral memory with the diagnostic log that the key configuration files match.The goal of the invention of the present invention is to provide a kind of method that vehicle-mounted fault diagnosis daily record exports automatically, the technical issues of diagnostic log for solving existing vehicle imbedding type system using technical solution provided by the invention needs to read by PC serial ports or diagnostic equipment.
Description
Technical field
It is exported automatically the present invention relates to vehicle-mounted embedded system technical field more particularly to a kind of vehicle-mounted fault diagnosis daily record
Method.
Background technology
In vehicle imbedding type system, when system breaks down, at present method be need through the serial ports of PC computers or
Specific diagnostic equipment could read the diagnostic log of the system failure, cause pretty troublesome in after-sale service, while cost is very high.
Invention content
The goal of the invention of the present invention is to provide a kind of method that vehicle-mounted fault diagnosis daily record exports automatically, using the present invention
The diagnostic log that the technical solution of offer solves existing vehicle imbedding type system needs to read by PC serial ports or diagnostic equipment
The technical issues of taking.
In order to solve the above technical problem, the present invention provides a kind of method that vehicle-mounted fault diagnosis daily record exports automatically,
It is characterized in that：Include the following steps：
1), a system thread for monitoring peripheral memory is created
2), the system thread detects the key the configuration files whether peripheral memory is stored with troubleshooting log；
3), detect that the peripheral memory is stored with key configuration files, vehicle imbedding type system verification and reading diagnosis
The key of daily record configures content；
4) key configuration contents and the diagnostic log that the key configuration files match, are output to peripheral hardware storage
Device.
Preferably, in step 2, the peripheral memory is USB flash disk or SD card.
Preferably, there are the delay times of 500ms between step 1 and 2.
From the foregoing, it will be observed that following advantageous effect can be obtained using the present invention：The invention detects that the peripheral hardware of vehicle mounted multimedia
The daily record of onboard system fault diagnosis is output to outside by memory automatically there are when the key configuration files of troubleshooting log
In storage device, solves the problems, such as vehicle-mounted traditional fault diagnosis daily record output, can will be by easy peripheral memory
System troubleshooting log is read out, convenient for analyzing vehicle-mounted fault message.
Description of the drawings
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, the present invention will be implemented below
Attached drawing is briefly described needed in the description of example or the prior art.It should be evident that the accompanying drawings in the following description
Only a part of the embodiment of the invention, for those of ordinary skill in the art, in not making the creative labor property
Under the premise of, other drawings may also be obtained based on these drawings.
Fig. 1 is process chart of the embodiment of the present invention.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes.Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without creative efforts
Embodiment shall fall within the protection scope of the present invention.
In vehicle imbedding type system, need serial ports or specific diagnostic equipment by PC computers that could read system event
The diagnostic log of barrier.
Fig. 1 is referred to, in order to solve the above technical problem, the present invention provides a kind of vehicle-mounted fault diagnosis daily records to export automatically
Method, include the following steps：
1), a system thread for monitoring peripheral memory is created
2), whether system thread detection peripheral memory is stored with the key configuration files of troubleshooting log；
3), detect that peripheral memory is stored with key configuration files, vehicle imbedding type system verification and reading diagnostic log
Key configure content；
4) key configuration contents, are output to peripheral memory with the diagnostic log that key configuration files match.
Wherein, in step 2, peripheral memory is USB flash disk or SD card.There are when the delay of 500ms between step 1 and 2
Between.
Method provided in this embodiment detects key of the peripheral memory there are troubleshooting log of vehicle mounted multimedia
When configuration file, the daily record of onboard system fault diagnosis is output on External memory equipment automatically, solves vehicle-mounted tradition event
The problem of hindering diagnostic log output, system fault diagnosis log read can be come out, be convenient for by easy peripheral memory
Analyze vehicle-mounted fault message.
Embodiments described above does not constitute the restriction to the technical solution protection domain.It is any in above-mentioned implementation
Modifications, equivalent substitutions and improvements etc., should be included in the protection model of the technical solution made by within the spirit and principle of mode
Within enclosing.
